Modernizing Transportation Payments

AtoB is building the financial infrastructure for the transportation industry, often described as the "Stripe for Transportation." The company provides modern payment solutions, including universally accepted fleet fuel cards with zero fees, robust discount programs, and industry-leading fraud protection. With a recent $130 million Series C funding round pushing its valuation to $700 million, AtoB is rapidly scaling its impact on logistics, where the timely movement of capital is critical for efficient supply chains.

A Culture of Impact and Efficiency

The culture at AtoB centers on solving real-world problems for a traditionally underserved industry. Employees highlight the fast-paced, mission-driven environment where cross-functional collaboration is key. Engineering and product teams work closely to build scalable, secure infrastructure, while go-to-market teams focus on delivering tangible value to fleet operators. The environment is highly dynamic, requiring adaptability and a strong bias for action, typical of high-growth fintech startups.

What You'll Actually Do

At AtoB, the work varies significantly by role but shares a common focus on scaling operations and enhancing the product suite. Engineers work on building robust payment processing systems, developing fraud detection algorithms, and integrating with diverse financial networks. Product managers focus on user experience, ensuring that fleet managers and drivers have intuitive tools for expense management and payroll. Go-to-market roles, such as sales and marketing, involve educating the market on modern financial tools and driving adoption among trucking companies of all sizes.

Compensation & Benefits

AtoB offers competitive compensation packages typical of well-funded San Francisco startups. Software Engineers can expect total compensation ranging from $178K to $249K+, while Product Managers see median packages around $275K. Compensation includes a mix of base salary, equity, and comprehensive benefits. The company supports a hybrid work model, with a strong presence in the San Francisco Bay Area and New York, offering flexibility while maintaining in-person collaboration opportunities.

The Interview Process

The interview process at AtoB is rigorous and role-specific. For engineering roles, candidates typically go through 4-5 rounds, starting with a recruiter screen, followed by technical interviews focusing on past work, coding, and system design. Interviewers probe deeply into the intricacies of previous projects. For business and operations roles, the process often includes case studies or take-home exercises, alongside behavioral and cross-functional interviews to assess cultural fit and problem-solving capabilities.

Why Join / Why Not

Joining AtoB offers the opportunity to modernize a massive, critical industry with a product that provides immediate, measurable value to its users. It is an excellent fit for those who thrive in high-growth environments and want to work on complex financial infrastructure. However, the fast-paced nature of a scaling startup may not suit everyone. The rigorous demands and the need for rapid execution require a high level of commitment and resilience, making it less ideal for those seeking a highly structured, predictable corporate environment.
